    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
    - Figure 1 shows an elevational view of an embodiment of the manual actuator support for automatic screwdrivers according to the invention.
    - Figure 2 shows the diagrams corresponding to the position tasting device and the position control device.
    Preferred embodiment of the invention.
    In the exemplary embodiment shown in Figure 1, the hand-operated support for automatic screwdrivers; It is schematically represented by a movable bar (1) for the fastening of an automatic screwdriver (D) and its manual placement, by the operator, in different working positions.
    The support is provided with an automatic screwdriver position control system (D) comprising: a sensor device (2) of the actual position of the automatic screwdriver (D), and a position control device (3).

    The pick-up device (2) of the real position of the screwdriver (D), is mounted on the movable bar (1) and, as can be seen in Figure 2, comprises: - sensors (21, 22) suitable for picking up of parameters corresponding to a series of real working positions of the automatic screwdriver during a specific assembly; - a microprocessor (23) configured for the reception and treatment of the position parameters captured by the sensors (21, 22), - an electrical power supply (24) and - communication means (25) suitable for the transmission of the parameters of the actual working positions of the automatic screwdriver to the position control device (3).
    In this exemplary embodiment said communication means are of the wireless type, for example by bluetooth, and the sensors (21, 22) are constituted by a digital inclinometer and altimeter.
    The position control device (3) comprises: - a microprocessor (31) with a memory suitable for storing a series of preset working positions of the automatic screwdriver for a specific assembly; - communication means (32) for receiving the actual position parameters of the automatic screwdriver supplied by the pickup device (2); an interface (33) for the introduction and recording of preset positions, to be occupied by the automatic screwdriver (D) during the realization of a specific assembly and a power supply (34).
    The position control device (3) is provided with a specific software program for the comparison of the parameters of the real position of the automatic screwdriver (D), collected by the sensor device (2), with the preset working positions and stored in the control device (3); and the firing of an error notification in case the real positions that the automatic screwdriver occupies, during the operation of the same by the operator to tighten some screws in a certain assembly, do not correspond to the sequence of preset positions and stored in the control device (3) for said assembly.
    In this way, once a series of automatic screwdriver positions have been preset and stored to perform a certain assembly, the operator must follow the predetermined sequence so that if he does not do so he will be notified of an error message and cannot continue screwing.
    For example if you have to screw an airbag system that has four cross-located screws, if it is previously determined, through the stored positions, that you must first screw the one on the right and then the one on the left, the operator must follow the pre-established sequence, automatically detecting compliance or non-compliance with it.
